The chamber that fits your DUT today isn't always the chamber that fits your programme over its useful life. Four steps: usage profile, acquisition budget, operating cost, and the return on buying versus renting at 2, 3, and 5 years.

What are you actually testing?
Four questions. The answers shape every number in the next three steps.
What does the test article look like?
Does anyone need to physically enter the space during a test — for setup, monitoring, or staging?
How often will the chamber run?
Roughly how many years do you expect to keep using this chamber?

What it costs to get one installed
Ranges, not single numbers — chamber pricing varies by manufacturer, refrigerant type, and controller software, and most quotes omit the line items below the chamber itself.
Total acquisition range
—
Wide ranges reflect real variance across manufacturers and regions — not a calculation error. Get a written, itemised quote before treating any number here as a budget.
What it costs to keep running
The number most budgets miss. Annual cost scales with usage frequency — and walk-in rooms scale worse than reach-in chambers per cubic foot, because conditioning a larger volume costs more regardless of how full it is.
Estimated annual operating cost

Buy, or rent for now?
Renting avoids the capital cost and the maintenance burden — but past a certain utilisation level, it costs more than ownership. Here's where that line falls for your profile.
